World’s Longest Wind Turbine Blades

Made in Denmark

2013.08.06

The 83.5 meter long blades blades from Danish SSP Technology have been transported to Scotland last month and will be installed on a 7 MW test offshore turbine for Samsung Heavy Industries’ first offshore wind energy project, targeted to start in 2015.

With a rotor diameter of 171.2 m, each wind turbine blade weighs 30 tonnes. The 7 MW wind turbine equipped with the three blades can, in a matter of just 30 minutes, produce the amount of energy equivalent to the annual energy consumption of an average family

Transportation of blades

The root diameter of the blades is only 4.2 meters, which makes it ideal to facilitate smooth road transportation. The blades are transported on heavy load trucks from SSP Technology’s production site in the southern part of Funen, Denmark. In the port of Esbjerg on the Danish west coast, the blades are loaded onto special vessels for the sea transport to the installation site of the Scottish coast.

Close cooperation between SSP Technology and Samsung Heavy Industries

Engineers from Samsung Heavy Industries joined SSP Technology’s design office for multiple months in the initial design phase and also followed the onsite the manufacturing process closely at SSP Technology’s factory. SSP Technology’s engineers and factory managers will through a technology transfer process assist SHI in starting up the serial blade production in Korea using the mould set developed and delivered by SSP Technology.

SSP Technology has in partnership and co-operation with Samsung Heavy Industries executed the 7 MW blade project including blade design, tooling and mould manufacturing, production of test blade and prototype blade set and execution of static and fatigue testing within a very short time span.
